摘要
随机数的核心是数的不可预测性和不可重复性。它是密码学研究领域的一个关键问题,是信息安全的重要保障。本文基于布朗运动的无规则随机性,设计并制作了一种随机数的产生装置。该装置主要是通过跟踪做布朗运动的微粒轨迹变化,作为随机数的产生源。利用该实验装置取样537组数据分析了随机数的产生情况,发现其产生的十进制随机数概率基本相等,最大误差仅为0.017,可以满足真随机数不可预测性与不可重复性的需要。
The core of random numbers is the unpredictability and non-repeatability of numbers.It is a key issue in the field of cryptography research and an important guarantee for information security.Based on the randomness of Brownian motion,a device for generating random numbers is designed and fabricated.The device is mainly used as a source for generating random numbers by tracking the trajectory changes of particles doing Brownian motion.using the experimental device to sample 537 sets of data to analyze the generation of random numbers,it is found that the probability of the generated decimal random numbers is basically equal,and the maximum error is only 0.017,which can meet the needs of unpredictability and non-repeatability of true random numbers.
